The clinical and pathological features of 22 patients, 11 males and 11 females 17-70 years of age (48.0 +/- 16.0 years), with hepatic tuberculosis were reviewed. Five patients had no evidence of extrahepatic tuberculosis (local form), and 17 had the miliary form. The clinical features of the miliary and local forms were similar with pyrexia, abdominal pain, hepatomegaly and body weight loss as the main manifestations. The biochemical findings were also quite similar in reversed albumin and globulin (A/G) ratio (2.9/3.5 vs. 3.2/3.4 g/dl) and disproportionate elevation of alkaline phosphatase (ALP) in comparison with bilirubin values but lower levels of alanine aminotransferase (ALT) (40.4 +/- 51.0 vs. 170.8 +/- 209.4 U/l; p < 0.05) and ALP (208.5 +/- 138.9 vs. 389.5 +/- 271.1 U/l; p < 0.05) in the miliary form. Patients with the local form had higher albumin (3.2 +/- 0.8 vs. 2.9 +/- 0.7 g/dl), aspartate aminotransferase (AST) (160.4 +/- 221.7 vs. 65.9 +/- 69.7 U/l), and gamma glutamyl-transpeptidase (gamma GT) (217.0 +/- 144.0 vs. 136.0 +/- 92.1 U/l), although the differences were not significant. The histopathological features of the miliary form were also similar to the local form with granuloma, caseation, acid-fast bacilli, fatty change and portal fibrosis as the main findings. The local form revealed more severe signs of hepatocytic damage while the miliary form was more wasting. The results suggest that the miliary and local forms of hepatic tuberculosis had quite similar clinical presentations and pathological features. The biochemical tests suggesting hepatic tuberculosis were reversed A/G ratio and disproportionate elevation of ALP.

A squirrel monkey (Saimiri sciureus) presented with wasting, vomiting and diarrhoea. Haematology revealed elevation of creatinine phosphokinase, lactic dehydrogenase, alanine aminotransferase, amylase and lipase, together with azotaemia and hypoalbuminaemia. Prominent findings were chronic pancreatitis with acinar and ductal plugs, granulomatous and necrotizing peripancreatic steatitis, degenerative myopathy, testicular atrophy, candidiasis and bacterial necrotizing glossitis. Antioxidant analyses revealed low concentrations of serum vitamin E (and apparently A), hepatic selenium and hair zinc. Pancreatitis may have caused malabsorption and maldigestion, associated with deficiency of multiple antioxidants.

Previously we reported carbon tetrachloride-induced body weight loss in rats as a new model of wasting disorders. The oral administration of a low dose of carbon tetrachloride to rats reduced the body weight and food intake at 24 h with a minimal effect on plasma alanine aminotransferase activity. Tumor necrosis factor-alpha, and cyclooxygenase-1 and -2 mRNA expression in the brain was not affected by carbon tetrachloride. Zaltoprofen, which is a non-steroidal anti-inflammatory drug, prevented the carbon tetrachloride-induced body weight decrease, without preventing the carbon tetrachloride-induced loss of food intake. The present results suggest the possible application of this drug for the treatment of wasting disorders.

Insulin resistance (IR) in the context of highly active antiretroviral therapy (HAART) is becoming more common in HIV-infected patients. Patients with chronic hepatitis C virus (HCV) infection have an increased risk of IR and type 2 diabetes mellitus. A cross-sectional study was performed to investigate whether chronic HCV infection constitutes a risk factor for IR in HIV-HCV-coinfected patients undergoing HAART. Inclusion criteria were positive HCV viremia and a sustained increase of alanine aminotransferase of at least twice the normal value. A total of 29 HIV-HCV patients, 76 HIV patients, and 121 HCV controls were tested for IR and body mass index (BMI). IR was measured using the homeostasis model assessment. In HIV-HCV and HIV patients, fat redistribution and lipid profile were assessed. There was no significant difference in age, CD4 cell count, HIV viral load, or duration of HAART between the HIV-HCV and HIV groups. HIV-HCV patients and HCV controls had a significant increase in IR when compared with HIV patients (0.25 +/- 0.28 and 0.21 +/- 0.34 versus 0.04 +/- 0.37; p =.01 and p =.003, respectively). Lipoatrophy was observed more frequently in HIV-HCV patients in comparison with HIV patients (41% versus 14%; p =.003). In HIV-HCV patients, total cholesterol and triglyceride levels were significantly lower than in HIV patients. In multivariate analysis, IR, BMI, triglyceride levels, and peripheral fat wasting were the independent variables associated with HCV infection. Our findings suggest that chronic HCV infection is a significant factor associated with the development of metabolic abnormalities and with modifications in body composition in HIV patients receiving antiretroviral treatment.

Since phenoxazine is an essential structure of actinomycin D, which exerts a strong anticancer effect, we examined the anticancer effect of 2-aminophenoxazine-3-one (Phx-3) on mouse malignant melanoma B16 cells in vitro and in vivo. Phx-3 inhibited proliferation of the B16 cells in a dose-dependent manner in vitro. We furthermore studied the in vivo effects of Phx-3 on mouse malignant melanoma B16 cells transplanted in female C57BL/6Cr Slc mice. Treatment with Phx-3 (0.5 mg/kg) completely suppressed the growth of mouse malignant melanoma B16 cells transplanted in mice as compared with the control group. Phx-3 was found to exert few adverse effects, in terms of bodyweight loss, changes in serum levels of blood biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), blood urea nitrogen (BUN) and creatinine, dysfunction of the liver and the kidney examined by pathological methods, piloerection and wasting, when mice were treated with a dose of 0.5 mg/kg. These results suggest that Phx-3 may be used to treat patients affected by malignant melanoma in future.

The aims were assessing liver function tests (LFT) in women with congenital adrenal hyperplasia (CAH) on glucocorticoids. Sixty-one women with genetically verified CAH due to 21-hydroxylase deficiency, aged 18-63 years were compared to 61 controls. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT), anthropometry and fat mass (dual energy X-ray absorptiometry) were measured. ALT and GGT were higher in the entire patient group (p=0.01 and 0.002); AST, GGT and ALP in patients > or =30 years (p=0.007-0.045); all LFT in salt-wasting (p<0.001-0.042); GGT in simple virilizing (p=0.008); ALT, GGT and ALP in Null/Null genotype (p=0.018-0.040); ALT and GGT in I2splice genotype (p<0.001 and 0.011). Using a recently proposed cut-off level for ALT (>0.317 microkat/L), 54% of patients vs 23% of controls had elevated levels (p=0.028). In patients, GGT and ALP correlated with waist circumference and with total body and trunk fat (r=0.274-0.406, p=0.001-0.043). However, ALT, GGT and ALP were increased even in non-obese patients (waist circumference < or =88 cm and body mass index <30 kg/m(2)) (p=0.012-0.045) mainly attributed to the patients > or =30 years who also demonstrated elevated insulin levels and HOMA-indices. In conclusion, compared with controls, women with CAH have higher LFT, in particular patients > or =30 years and those with severe forms, probably reflecting a higher lifetime glucocorticoid exposure. LFT were positively correlated to measurements of body fat. These women might have increased frequency of NAFLD. The finding of higher LFT also in non-obese patients suggests that not only central obesity but also glucocorticoids per se may influence.

Childhood malnutrition is a problem in developing countries, and pathological changes in digestive organs such as the intestine and liver are poorly understood. An animal model to study the progression of severe acute malnutrition could elucidate pathological changes in the intestine and liver. We sought to characterize growth and clinical changes during malnutrition related to structural and functional indices in the intestine and liver. Newly weaned piglets were given ad libitum access to a maize flour diet (MAIZE, n=9) or a nutritionally optimized reference diet (REFERENCE, n=12) for 7 weeks. Growth, hematology and clinical biochemistry where recorded weekly. After 7 weeks, the MAIZE pigs had lower body weights than the REF pigs (8.3 kg vs. 32.4 kg, P < 0.001), indicating severe stunting and moderate to severe wasting. This was paralleled by lower values for hematocrit, hemoglobin and mean cell volume in MAIZE vs. REFERENCE (P < 0.01), indicating anemia. Although the observed temporal changes in MAIZE were associated with atrophy of the small intestinal mucosa (P < 0.001), digestive enzyme activity was only marginally reduced. Serum alanine aminotransferase, bilirubin and albumin were increased in the MAIZE pigs (P < 0.001), and the liver had a vacuolated appearance and tendency toward increased triglyceride content (P=0.054). We conclude that liver and intestinal indices are compromised during malnutrition and are associated with temporal changes in growth and hematological and biochemical endpoints. The pig model is relevant for malnourished infants and can act as a valuable tool for understanding the pathophysiology of malnutrition.
